operation should resume after your vehicle
is left undisturbed for 8 hours. Make sure that you dispose of old batteries
in an environmentally friendly way. Seek
advice from your local authority about
recycling old batteries.
If storing your vehicle for more than 30 days
without recharging the battery, we
recommend that you disconnect the battery
cables to maintain battery charge for quick
starting.

GENERAL INFORMATION
The recommended tire inflation pressures
are found on the Tire Label which is located
on the B-pillar or the edge of the driver door.
This information can also be found on the
Safety Compliance Certification Label, affixed
to either the door hinge pillar, door-latch
post, or the door edge that meets the
door-latch post; next to the driver’
s seating
position.
We strongly recommend maintaining these
tire pressures at all times. Failure to follow
the tire pressure recommendations can
cause uneven treadwear patterns, reduced
fuel economy, and adversely affect the way
your vehicle handles.
Note: Check and set the tire pressure at the
ambient temperature in which you are
intending to drive your vehicle and when the
tires are cold.
Note: Check your tire pressures at least once
per month.
If your vehicle has a spare tire, set the
pressure to the highest value given for your
vehicle and tire size combination. Use only approved wheels and tire sizes,
using other sizes could damage your vehicle.
If you change the diameter of the factory
installed tires, the speedometer may not
display the correct speed. Take your vehicle
to an authorized dealer and have the engine
management system reprogrammed.
If you intend to change the size of the factory
installed tires, check the suitability with an
authorized dealer.
Additional information related to the
functionality and maintenance of your tires
can be found in the Wheels and Tire section.
See Tire Care (page 356).
Notice to utility vehicle and truck
owners WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death. WARNING:
In a rollover crash, an
unbelted person is significantly more likely
to die than a person wearing a seatbelt.
Utility vehicles and trucks handle differently
than passenger cars in the various driving
conditions that are encountered on streets,
highways and off-road. Utility vehicles and
trucks are not designed for cornering at
speeds as high as passenger cars any more
than low-slung sports cars are designed to
perform satisfactorily under off-road
conditions.

Axle and PTU maintenance: The Power
Transfer Unit (PTU) and rear axle (AWD only)
in your vehicle does not require any normal
scheduled maintenance. The PTU lubricant
may be more likely to require a fluid change
if the vehicle has extended periods of
extreme or severe duty cycle driving.
Changing or checking the PTU lubricant is
not necessary unless the unit has been
submerged in water, shows sign of leakage.
Contact your authorized dealer for service. California fuel filter replacement: If you
register your vehicle in California, the
California Air Resources Board has
determined that the failure to perform this
maintenance item does not nullify the
emission warranty or limit recall liability
before the completion of your vehicle's
useful life. We however, urge you to have all
recommended maintenance services
performed at the specified intervals and to
record all vehicle service. Engine air filter and cabin air filter
replacement: The life of the engine air filter
and cabin air filter is dependent on exposure
to dusty and dirty conditions. Vehicles
operated in these conditions require frequent
inspection and replacement of the engine
air filter and cabin air filter.
